So I made an Excel file compiling 16 different "Best Films of the Decade" lists and made a Top 150 based on which movies appear on the most lists. I compiled the masterlist using lists posted by Ain't It Cool News, Entertainment Weekly, Film Comment, Film Talk, Hollywood Reporter, The Guardian, IMDb, The Onion, Reverse Shot, PasteMagazine,Times Online, and the Village Voice, as well as film critics Roger Ebert, Jim Emerson, Michael Philips, and AO Scott. I've underlined, bolded, or italicized the ones I've seen, depending on which works in LiveJournal today.
This is what I do when I'm eating my breakfast.
Anyway, my picks are coming later.
